Total number of concealment frames divided by total number of speech
frames that were received from start of the voice stream.
Cumulative Conceal Ratio

might be required to accumulate 3 seconds of active speech.
Interval Conceal Ratio
Highest interval concealment ratio from start of the voice stream.Max Conceal Ratio
Number of seconds that have concealment events (lost frames) from the start
of the voice stream (includes severely concealed seconds).
Conceal Seconds
Number of seconds that have more than 5 percent concealment events (lost
frames) from the start of the voice stream.
Severely Conceal Seconds

running average of the round-trip delay, measured when RTCP receiver report

View the Customization State in the Configuration Utility
After the RC download from the EDOS server completes, you can view the customization state of a phone
using the web interface.
Here are the descriptions of the remote customization states:
• Open—The phone has booted for the first time and is not configured.
• Aborted—Remote customization is aborted due to other Provisioning like DHCP options.
• Pending—The profile has been downloaded from the EDOS server.
• Custom-Pending—The phone has downloaded a redirect URL from the EDOS server.
• Acquired—In the profile downloaded from the EDOS server, there is a redirect URL for provision
configuration. If the redirect URL download from the provisioning server is successful, this state is
displayed.
• Unavailable—Remote customization has stopped because the EDOS server responded with an empty
provisioning file and the HTTP response was 200 OK.
